CAR-RO OF.

Application filed October 9, 1916. Serial No. 124,476.

To aZZ lwhom 15 may concern:

Be it known that I, WALTER P. MURPHY, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois', have invented a new and useful Improvement in Car-Roofs, I

of which the following is a specification.

This invention relates to outside metal car roofs made of metal sheets which are interloeked at theiredges and which are supported upon a suitable substructure.

The invention has to do particularly with the means for securing the roof sheets in place upon the ear, and with the means for preventing water from getting beneath the edges of the roof sheets and into the, ear along the ridge andeaves.

The objects of the invention are to prevent wear on the roof sheets from the fastenings, to avoid straining the sheets from deformations of the car body or the shocks of service, to provide for the easy inspection and for the ready replacement of damaged sheets, and to make a, neat appearance,

The invention consists in connecting the sheets by watertight joints, and 'securing them to the substructure at the ridge so that they cannot move, but holding them down at the ends of the car and at the eaves in such4 a way that they can move relatively to the substructure. The invention further consists in providing caps for the ends of the car and flashings at the ridge and eaves for holding the edges oi the roof sheets and which' also' assist in keeping-water out of the ear at these places.

Further objects and details ot the invention appear inv connection with the following description of the cai' roof illustrated in the accompanying drawings; and what the invention consists in is further defined in the appended claiiiis. l

In the drawings wherein the saine reference characters are used to designate the saiiul parts in the several views,

Figure 1 is a plan view of the end of' a car, the running boards and rootl sheets be? ing broken awa)y 1o disclose the ridge and eaves [lashings and the roof substructure;

Fig. 3 is a cross-section through the eaves, on the line 3-3 in Fig. 1; and

Fig. 4 is a eross-section through the ridge, on the line 4-4 in Fig.' l.

The car shown in the drawings has a wooden roof substructure comprising a ridge pole 11 and sheathing boards l2 supported upon the side plates 13 and end plates 14 of the ear and the suitably spaced ear lines 15. Thel invention is not restricted to any particular kind of ear or type of roof substructure, however.

The metal roof consists of sheet metal roof sheets 16 which are arranged in two rows, one on each side ofthe ridge, the sheets in each row being connected by snugly fitting inverted U-shape side marginal flanges 17 which telescope together to form interlocking standing seams. The ridge ends of thereof sheets have inverted V-shape anges 18 which nest together one on top of the other, and lit over the middle rib`19 of the ridge flashing strip 20 which is made'in one piece oi' in lapping sections nailed along the ridge from endto end oi the ear, unlike the construction shown in P. H. Murphy Patent No. 489,322, wherein.

the ridge Ts are separate, of roof sheets.

The eaves ends of the roof sheets are turned under, forming iianges 2l which hook under the rebent inner edges 22 of the eaves flashing stri s E23. -The outer edges of the eaves flashing strips are turned down over the corner ofthe ear and are nailed or otherwise secured to the side of the car. The eaves strips extend from end to end of the ear. Corrugations 24 at intervals along the eaves strips stifl'en them against bending and lifting up from the `ear at their inner edges, thereby holding down the eaves ends of the roof sheets.

Corner caps 25 are arranged at 'the ridge corners of the roof sheets, closely embracing the ends of the side and ridge seams. These corneicaps are' held in place by bolts 26 which extend through the ridge pole. The bolts 26 also secure the running board saddles 2'? to which the running boards 28- one for each -pair are fastened. The ends of the running boards project beyond the ends of the ear and are supported by cross pieces 29 and iron braces 30 which are bolted to the ends of the ear beneath the roof.

The end roofsheets 31 terminate short ot the end of the car, and overlap the end flashing strip The inner edge of the end dashing strip is turned up and` bent back over the iashing strip to form alip 38 upon which the edges of the end root' sheets rest. This lip 33 also keeps water from running under the edges of the `end roof sheets and thus into the ear. End caps 34 at each end of the car cover the end flashing strips 32 and edges of the end roof sheets, The end caps and end flashing strips are turned down oi'er the ends of the car and nailed in place. The end caps have trans- .verse corrugations 35 for stitl'ening them andfpreventing their inner edges from liftlng up. i

This arrangement of the side and end eaves lashings `and fastenings permits the rootl sheets to nieve upon the substructure at all points except along the ridge, and thus distortions of the car which result in movements of the ends and sides-ot the car with respect to the ridge have ne harmful etl'ect upon=the root sheets. The rootl sheets are held i1. proper alinernent upon the substrueture by the ridge corner eapsand by their engagement with the ridge flashing strips, whereby all other'positioning means may be dispensed with, and wear and strains upon the root sheets due to contact with tasten- "iiigs along the eaves are eliminated.

It is evident that changes, may be made in the form and proportions ot theroot sheets, flashing strips and caps without affecting their functions, and the invention is not restricted to the particular details of construction shown inthe drawings.

I claim the following as my invention:

1. A metal car roof comprising roof sheets arranged in rows on each side oi the ridge, said roof-sheets having flanges along their side and ridge edges which are connected to l'orm seams, said rootshveels being tixedly secured tothe root' substructure along the ridge so as to maintain air unbroken line at their ridge ends and freely movable upon the root substructure along the eaves and at the ends oi' the ca r. whereby an alinement ot' the ridg,I ends ot the roo'l sheets is maintained notwithstamling the distortion 'oli the sides and ends of the ear.v

. 2. A metal car root'` comprising root sheets arranged erosswise ol the ear, said roof sheets having flanges along their side edges which are connected by a teleseoped and interim-iced joint to form seams, said roof sheets being ixedly secured to the roof substructure along the ridge so as tomaintain an unbroken line at their ridge ends and freely movable upon the 'roof substructure alongfthe eaves and-at the ends of the car, whereby alinement'of the ridge ends of the roof sheets is maintained notwithstanding the distortion of the sides and ends of the car.

3.
